Is it better to troll shallow cranks with weight, or use deep divers?

Answer:
Choosing the right crankbait really has more to do with the action as it relates to water temperature. For instance, if the water temperature is below 50 degrees, that’s when I use subtle action, shallow diving minnow style lures like the Berkley Flicker Minnow. If the fish are deeper than the baits will run on their own, then I will add Snap Weights. Once the water warms to above 50 degrees, then I will switch to more moderate action baits like the Berkley Flicker Shad. Even though these lures dive deeper on their own, there are still times when it will be necessary to use Snap Weights to get them to the desired depth. The larger diving lip on these baits give them a more aggressive wobbling action that is deadly in warm water, where as, the smaller lipped minnow baits have a more seductive “top-to-bottom roll” that usually triggers more walleyes in cold water.
